Movie Theatres & Auditoriums

Theater buildings present a unique challenge when selecting a heating and air conditioning system to provide proper ventilation.

Theater owners face the issue of increasing amounts of ventilation air (as recommended by ASHRAE Standard 62 and required by revised building codes) without tripling the cost of the system and its cost of operation. In addition, theaters have several types of rooms around the main atrium including lobbies, projection rooms and restrooms, which have their own ventilation and temperature requirements. Proper humidity and temperature control between these areas requires special attention. Humidity, not just temperature, has an important impact on human comfort.


Conventional air conditioning systems use cooling coils to adjust humidity levels, but that approach causes problems. Overcooling the air to eliminate moisture causes the theater to feel cold and clammy.


Movie theaters have intermittent occupancy which results in peak ventilation requirements during times of off-peak thermal loading.

Munters dehumidification products can lower space humidity and provide proper ventilation while reducing energy costs and increasing patron comfort. By using a Munters dedicated outdoor air system (DOAS), energy costs can be maintained while providing your theater with required ventilation air. Combining desiccants with energy recovery allows the DOAS system to provide a host of benefits:

  • Low-cost code compliance
  • Dry, healthy duct work
  • Increased cooling COP
  • Retrofit applications for IAQ
  • Energy recovery
